Yes, Reptilio is a beast when it comes to meter management, in that he always manages to have at least one bar. I use his Xray more than anybody elses bcuz of the aforementioned reasons as well as the fact that it goes full screen. People are quick to throw a projectile at full screenAlthough Reptile's Ex moves are really helpful, notably Ex slide and Ex spit, his X-Ray can be really useful because it goes through projectiles and can grab the opponent in the air, so I use it when I feel like surprising my opponent by breaking through a projectile and stabbing his eyes, muahahaha! Love that X-Ray
Plus, Rep build meter so insanely fast that you can be really generous with meter usage and still do fine, at least from what I know.
